SWITCH STAND.

Application filed March 18, 1927.

to control the movements of movable switch points of a mine track.

The primary object of the invention is to provide means for permittingthe wheels of a car passing over the track in one direction, to move theswitch points to permit the car to pass over the rails without danger ofderailment.

A still further object of the invention is to provide means whereby theswitch points may be manually operated to set the switch.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure 1 is a plan view illustrating a switch constructed in accordancewith the invention.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 8 is a sectional view taken at right angles to Figure 2.

Referring to the drawing in detail, the reference character 5 designatesthe rails of a mine track, and the reference character 6 designates themovable points or sections of a switch.

The rails are supported on the ties 7 which also act as a support forthe switch box 8, the ties being shown as exceptionally long andextended appreciable distances beyond the rails.

The switch box 8 is provided with lateral flanges 9 that rest on theties 7 the flanges being supplied with openings to receive bolts, notshown for securing the switch box in position. The movable members 6 areactuated by means of the bar 10, which is provided with upstanding pins11 and 12 respectively that engage the inner edges of the movablemembers 6 so that movement of the bar will result in a relative movementof the movable members 6 to set the switch or to return the switch toits initial position after a car has passed thereover.

Connected with the bar 10 is an operating a railway switch, a switchbox, rods mounted Serial No. 176,703.

lever 13 that has a forked end 1 1 connected with the ear 15 thatextends upwardly from the operating lever 16 at a point in spacedrelation with the inner end of the lever.

This lever 16 has a bifurcated end 17 provided with openings toaccommodate the shaft 18 positioned in the inwardly extended sections 19of the T-shaped members 20, so that the operating lever 16 may be swungupwardly from a position as shown by F igure 1 to a position so that thelever 16 rests in a notch formed in the opposite end of the switch box,thereby operating the movable switch section.

The T-shaped members 19 embody tubular sections 21 that accommodate therods 22 arranged in spaced relation with each other and supported withinthe switch box, the ends of the rods extending through the end walls ofthe switch box. Mounted on these rods are coiled springs 23, which bearagainst the ends of the tubular members that are mounted for slidablemovement on the rods, the springs acting to normally urge the tubularmembers to their initial positions.

A weighted handle indicated at 24: is pro-- vided at the out-er end ofthe lever 16 and affords means whereby the switch may be manuallyoperated. From the foregoing it will be obvious that when the switch isset in a manner as shown by Figure 1, a car moving in the direction ofthe arrows as shown by Figure 1 will move into engagment with themovable switch rails moving them against the tension of the springs, andallowing the car to pass over the rails, with the result that thesprings will return the rails and switch operating mechanism to theirinitial positions after the car has passed tl'lBlBOVGl.

I claim:

1. In combination with the movable switch rails of a railway switch, abar connected with the switch rails for moving the switch rails, a linkconnected with the bar, a switch box, rods supported within the switchbox, tubular members mounted on the rods, coiled springs on the rods andengaging the ends of the tubular members for normally urging the tubularmembers to their initial posi tions and means for operating the tubularmembers and bar and link for setting the switch.

2. In combination with the movable rails of shaped members to theirinitial positions, and means for transmitting movement of theT-shapedmembers to the switch rails.

In testimony that I claim the foregoing as my own, I havehereto-ailixecl my signature.

JOSEPH TRUSCH.
